Removing Damaged Connecting Blocks

In some cases, a connecting block becomes damaged and must be removed.

To remove a damaged connecting block, follow the steps below:

1Remove the wires or the patch cord from the connecting block.

■If you have Interconnect Wiring, use long-nosed pliers to remove the telephone wires, and tag the wires with tape to identify their positions.

■If you have Systimax wiring, pull off the patch cord.

2Place a 788K1 retainer tool against the conductor pairs beneath the connecting block to be removed. See Figure 3-40.

3Use pliers to grip the connecting block in the center. See Figure 3-40.

4Move the block gently up and down and pull it out.

5If a conductor wire is accidentally pulled from a block, pull it with the Iong-nosed pliers to get some slack.

Use your fingers to lay the conductor wire back in its slot in the index strip, and then reseat it with the D-impact tool.

6Seat the new connecting block by using the 788J1 impact tool.

7Replace the telephone wire onto the connecting block.

■If you have Interconnect Wiring, remove the tag from the telephone wires and use the D-impact tool to reseat the wires.

■If you have Systimax wiring, attach the patch cord to the connecting block.
